PLANTATION -- Second-grader Leonard Cox returned from school on Wednesday and faced a real-life test on the lesson of the day -- home safety.

In the back yard, he found his 2-year-old cousin drowning in the family pool.

``I just jumped right in,`` said Leonard, 7.

The Plantation Elementary School student pulled Andrew Williams from the water, dialed 911 and told the dispatcher what happened and the address -- following the rules for home emergencies that his class had learned that morning from McGruff the Crime Dog.

On Thursday, Plantation Elementary Principal Andrew O`Connell presented Leonard with a certificate during the school`s ``Good Morning`` show, broadcast to every classroom.

``That was really wonderful when you think about it, really something. We are very proud of him.``

By Thursday, Andrew was out of Plantation General Hospital, and back at his great-aunt`s home, where family members often gather, following Leonard around wherever he went.

About 4:30 p.m. on Wednesday, Leonard, a friend, Andrew and another toddler were playing in the backyard of the great-aunt`s house in the 400 block of Northwest 49th Avenue, Plantation. Andrew`s mother, Pauline Williams, 24, was in the house.

Leonard and his friend left the yard, and the toddlers were alone.

When Leonard returned to the pool area, he saw Andrew in the water.

``I said, `Andrew!` and jumped in the pool and got him out,`` Leonard said. Andrew`s mother then grabbed him and told Leonard to call 911.

Pauline Williams ran next door with Andrew to Dock and Wanda Brown`s home. The Browns and another neighbor, Maryann Degirolarmo, worked together to give the child mouth-to-mouth resuscitation and cardiopulmonary resuscitation until the paramedics came.

``His eyes were closed. He had no pulse, no heartbeat. He was dead. He was gone,`` said Wanda Brown, 32. ``I was praying that the baby would live and come back.``

A child also was saved from drowning in Coral Springs on Wednesday.

One-year-old John Trujello was pulled out of a lake at the 9100 block of Atlantic Boulevard by Karl Streible of East Lansing, Mich. The child wandered out of an apartment and fell into the complex`s lake. The child was released from Coral Springs Medical Center on Thursday morning.
